IN VITRO ANTIDIABETIC ACTIVITY AND PHYTOCHEMICAL ANALYSIS OF LUMNITZERA RACEMOSA LEAVES

Abstract

The present study was designed to evaluate the antidiabetic property and phytochemical composition of Lumnitzera racemosa leaves. Mangrove plant 
L. racemosa was collected in the month of May from Bhatye beach area Ratnagiri coast, Maharashtra, India. Leaves separated, powdered and exhaustive 
extraction was carried out in methanol, ethanol, ethyl acetate, and pet ether solvents with increasing polarity using Soxhlet apparatus and in vitro 
antidiabetic activity was determined by α-amylase and α-glucosidase inhibitory assays using acarbose as standard. Phytochemical analysis was carried 
out as per Wagner and Bladt (1996). Results have confirmed antidiabetic activity in methanol extract which was comparable to standard acarbose 
followed by ethyl acetate, ethanol and pet ether extracts. The phytochemical results showed the presence of flavonoid, saponin, essential oil, alkaloid, 
anthraquinones, bitter principles, phenol, triterpenoids, coumarin, and tannin in the leaves.
